How Toyota Hybrid System Work Part 4 Hybrid Brakes

[@survivordan2187]

It’s remarkable what Toyota has done since I’ve been with the company. (1999). They started hybrids with the Prius, made it work to perfection & then improved it! Now, we build dynamic force engines with almost 40% thermal efficiency and pair them with Toyota’s 5th generation hybrid system! I’ve heard people say Toyota is always “late to the party” with innovation. Well, there’s a reason for that; Toyota is a forward thinking company that instills the 80% planning and 20% doing philosophy until things are perfect and reliable. Thanks AMD for the wonderful videos!

[@AveiroDan]

Great video series on Toyota hybrids, I really enjoy them. I have a 2014 Camry SE Hybrid with 110,000 miles. When I took it in for the 100k service, the tech mentioned that whoever did the break job on my Camry did a fantastic job....I had to think about it & then told him they had never been done! This video explains why!

[@Nwwoods]

My Camry 220k still original, redoing them now…

[@christianrancourt7087]

Thanks for the explanation, the sales men at dealerships should watch this, because most don't understand and don't explain this right.

[@william6765]

I will be getting a 2022 Lexus NX 350 hybrid at some point this year and really enjoyed this. I learned that stopping gradually will not only charge the battery but also make my regular brakes last a long time!!

[@smaxwell4062]

I guessed what the buzzing noise is. I wish the hybrid display showed which braking system is working 💪. I love this engineering 🤩

[@GLC-1979]

Hybrid Assistant APP for your phone...shows when service brakes are used.

[@dj3114]

Always wondered what the buzzing was when the door was opened, but didn't worry about it because knowing there was a good reason and am now glad to know what it is. My bride (40 years) just heard him and said "You're obsessed with listening to that guy". My reply was that I always gravitate to content where valuable information is learned.

[@danbui3411]

I learned so much about hybrid brakes today - and I have owned my 2014 Camry hybrid for 6 years and knew nothing about it until today. Thanks.

[@jamesclark5461]

Finally a simple explanation why my brakes are still in good shape after 165K miles on my 2009 Camry Hybrid. Many thanks!!!

[@Machaing]

Hello from France 2nd hybrid toyota that I own, I always noticed this pump whistle when I opened the driver's door but I had never made the relation with the braking system. However, I own a BMW motorcycle that has a braking system controlled by solenoid valves that you hear at every brake! Thanks to you, I will go to bed less stupid tonight.

[@anthonyharvey5250]

Thanks 🙏🏾 for the simple lessons on the function of hybrid system. I have been checking out more complicated videos on this subject and I can say that w/out your videos I would be lost, but because I have been watching your tutorials they make understanding hybrid much more easier. You’re among the best. Much blessings much love.

[@liakoel]

In my 2018 Yaris there is a buzzing sound but in my 2023 Corolla there is not! I think because it's a newer hybrid version! Good job Toyota in general! I'm fascinated of how hybrids work!

[@AriaLaurel]

Not only was this a great overview of the system, but it answered the question I didn't even know I needed to ask about the random short buzzing sound!

[@jamesrose1191]

Great explanation, I have had multiple Prius’s and never knew that’s how they worked. I never had a problem with breaking, accelerating was a different matter. I floored the pedal in an emergency and had to wait short period of time for the car to start to accelerate. Scared the poop out of me and after a while I sold it and ended up with a Tesla. No problem accelerating now.

[@carlosgomes634]

One thing I find about my 2014 Prius V Braking system is that while I’m braking, if the car hit’s a bump in the road it will actually accelerate and lunge the car forward, and require me to apply additional brake force in that moment, it only happens intermittently, but is a bit irritating, thanks for your very informative videos, they will help people to understand their vehicles and save some money.

[@aspecreviews]

Bumps cause power surges. To protect the hybrid system, the regenerative braking system turns off.

[@jaimelima2420]

In the RAV4 the the traction control flashes in these cases. Not sure if it does real compensation too or not.

[@robelrobu917]

100% same on my 2014 Prius two. I even thought it was somehow my reflex but now I know

[@GaryAttaway]

I always wondered what that sound was. Thanks for explaining!

[@billliebert122]

Thank you for your explanation. I had wondered how they work. By the way, my 2014 Avalon Hybrid has just turned 150,000 miles. Every 5,000 miles I have the local dealer change the oil and rotate the tires. And I'm still told no brake work needed!

[@craigyamasaki4236]

Thank you for another great video! I now know what that noise is when I sometimes open a door on the car when it is not running. I've been wondering about it for 11 years since we purchased our first 2010 Prius, then our RX450h, and now our Prius Prime. Your videos are awesome!

[@pecan11]

Talk about GENIUS! I never have had problems and I am not worried bec I ALWAYS keep two ways out of any driving situation.

[@rondini2]

I’ve heard that buzz when I get in the car before I even hit the start button. I figured it was the system getting ready or resetting something on the engine. But it’s the brake system pressurizing! Now I know! Thanks

[@sbromose1]

I made an attempt. Drove 80-100 km / h put it in neutral and braked down evenly and hard, sometimes only on the P brake and it helps a lot. I will do this regularly, then the rust will probably disappear completely.

[@telsys]

Thanks for explaining, I now understand the breaking "anomaly" on my 2020 RAV4 Hybrid. OTOH, it teaches you good driving habits.

[@darkbyte2005]

This is absolutely fantastic video and i have a Lexus hybrid and i always wanted to know what that noise was when opening the door.. now i know.. Thank you so much for this series of walk through of the hybrid system

[@johnkeepin7527]

Good description. It’s a bit more complex than that, though. You did mention the interface with the ‘anti-lock braking system (ABS)’, but it also has (at least in my Yaris from 2017) ‘Brake assist’ which (verbatim from the manual): “Generates an increased level of braking force after the brake pedal is depressed when the system detects a panic stop situation ”. It’s also connected to the “pre-crash safety system (PCS)” so that the brake pressure is ramped up automatically. Again, from the manual “If the system determines that the possibility of a frontal collision with a vehicle is extremely high, the brakes are automatically applied to help avoid the collision or help reduce the impact of the collision.” I’ve experienced it doing this, and it’s quite useful! Note that the model I have also has a ‘vehicle data recording’ device, which can record odds & ends like that, almost like a cut back version of an aviation “black box”, as it were. The other point to note is that it’s wise to avoid emergency stops if something is too close behind - it will ‘take over’ to some extent.

[@aurora571000]

Love your videos! I absolutely love my 2015 Prius, but my regular mechanic won’t touch it. I don’t trust dealers or most mechanics. (Due to dating a mechanic, who worked in his dad’s successful shop) I realized that if I wanted to continue driving Prius, I had to understand them and be more pro-active with the maintenance. And I want to return your greeting “the Lord bless you”.😊

Best Toyota Technician !!! Thank you.

[@funlovingJohn]

Thank you for the informitive info. on my brakes. I tested my brakes in my 2019 Avalon Hybrid, and after a drive around here in Los Angeles @ about 70F, I felt my rotors and found them cool. Regerative braking really works! My car was sitting in my garage for three days and after opening the door I could only hear the brake pump very close to the hood. I never heard it before. I guess the brake pump in Toyota's best car the Avalon is a little more refinded.

[@TheCarCareNut]

Regen braking is pretty impressive. The Avalon being a more heavily insulated car likely you won’t hear it as loud as some other models

[@leyland9999]

Great series! Thank you for this excellent channel. Now I understand what the strange sounds are and come from. I’m totally unfamiliar with the Toyota hybrid system or any hybrid system. I bought my brand new RAV4 in 2019. To be honest, it took a while before I really started to value this car due to all kinds of things that I simply didn’t understand e.g. why does it make noises not present on conventional cars. I’m a Ford guy, my previous car was a Kuga (Escape in de USA). The new Escape by the way copyed the Toyota hybrid system but is not available as a AWD. This was the reason I bought a RAV4, the only reason. Thanks to your video’s I value this car so much more and assured me this car is the right one for me.....Kind regards, Willem, Hekelingen, The Netherlands.

[@rondhole]

@@TheCarCareNut Thank you for the clear explanation. I am wondering why no brake fluid change recommendation in manual or maintenance schedule in USA. But in EU we have it every 2 years, not sure why but probably because of the unlimited speed limit in Autobahn and very sharp exit in almost most highway.

[@TheCarCareNut]

Thank you for watching my channel! So that remains a mystery typically brake fluid has enough moisture content to recommend replacement around 2-3 years

[@Nehoets]

Man, this is a great system. I bought a 3rd Gen Prius 5 years ago and it was 2 years old. The dealer I bought it from (Dodge dealer) said I would probably need a brake change soon, this was 2 years after purchase, then the car was 4 years old, 3 years later, a 7 year old car and I have not changed the brake pads, they just sit in the trunk.

[@cjsamtab7]

I must share that the CHR Hybrid I bought in April of 2018, saved me from crashing TWICE by other reckless motorists towards the tail end of 2018 ; see, as I was travelling along a highway at between 80 to 90kph and was executing an merge into an Exit Ramp, a light truck suddenly swerved out from its own merging out lane which then caused me to stomp on the brake pedal to avoid colliding into the truck's rear end. Guess what ; the CHR decided in a fraction a second to multiply my brake pedal pressure enormously when it detected insufficient foot pressure - possibly calculated by the front proximity and collision radar's data - and it brought my car to an abrupt stop dipping the front down significantly and eased off the moment I heard the first short squeak of tyre screech was beginning. My CHR was halted just 1 foot from the tailgate of the light truck. The second incident was similar in nature but caused by a car cutting into my lane due to the lack of foresight in planned lane selection. And again the on board computers decided I had a light foot and took safe control of the situation with not a squeak from the tyres. No regrets going Hybrid under Toyota.

[@Normlyabnrml]

I am new to your channel but I have learned quite a bit about not Hybrid. Don’t cringe, I have a 2007 Camry Hybrid. I learned from your channel that the buzzing I hear when I open my door in the morning is the brake actuator, I believe building pressure or something like that. Either way, that noise when I open the door has gone from maybe a couple seconds to several seconds. It has gotten considerably longer, also when the car is off or even in “ready” when I press on the brake it makes a tinging sound, if that makes sense and when I go to stop now it’s almost like a pulsating feeling that gets a little worse the harder I brake. I have an appointment with the Toyota dealer, but I wanted your opinion. :) Thank you

[@Normlyabnrml]

About MY Hybrid **

[@TheCarCareNut]

Hi! Sometimes air enters the system and makes the pump make a louder than usual noise. the first thing I would try to do in this case is bleed the brakes and see if it improves. If not and the dealership recommends an expensive ABS actuator I would not replace it at this point. If the brakes works well it might take a long time for it to completely fail.

[@StevenOsburn]

New RAV4 Hybrid owner here - 1 week old. Your video on brakes was awesome! I have more of your videos to watch, but do have a couple questions on braking - 1) Is there a way to tell which brakes are being used at the moment (regenerative or hydraulic)? For example, if I was going down a long steep road (like coming down a mountain pass) - I would think that at some point I should downshift if I'm using hydraulic brakes too much, but how would I know if I'm using hydraulic if there isn't an indicator that tells me which brakes I've been using? 2) Once the battery is fully charged, if the car is still going down a steep grade, does the regeneration stop and rely more on hydraulic? If the regenerative doesn't stop, but the power is not going to the battery, what happens to the extra power being generated?

[@TheCarCareNut]

Hi! There’s no direct indicator to know. If the battery is fully charged on the indicator charging stops and the hydraulic brakes are used to stop the car. But you’ll feel the transition between regen and hydraulic brakes when that does happen

[@jaimelima2420]

Hi, I had the same question on mine which I got about the same time you got yours. The ‘E’s on the trip screen (each full E is 50 Wh) are a good indirect way to have a feeling about how much break generation you are getting. The hybrid scoring feedback screen seems to score one well on cruise and bad on braking if the break pedal is pressed very lightly. If battery is full the computer could do some engine braking automatically, which can be done easily thru the eCVT (educated guess based on Prof. John Kelly’s videos).

[@future212]

Nice little car, congratulations, I have the same one but have it for over 6 years, it has now 281000 km and no issues, every service at Toyota, just the 12v battery died spontaneos with no warning a few months ago but it seemed it was the original battery for 9 years, so still impressive it lasted so long. By the way TCCN you should make a quick video about how to jump start your hybrid car without getting to your 12v battery (in my case the booth actually remained locked so couldn`t opened it)

[@mihai7558]

@@DreamLightIbiza Thanks! Mine has about 176000 km. Unfortunately I had an issue with it today. ABS, ESP, the red exclamation mark (parking brake) and an yellow exclamation mark lights turned on and won't go off. I was at the service and they said it's a faulty rear-left speed sensor. They ordered a new one and will change it, I hope it will be ok. I asked to replace the 12V battery too since sometimes the car is not starting from the first attempt (the "Ready" light doesn't turn on).

So the sensor was replaced with a new one and the issue went away.

[@mihai7558]

@@TheCarCareNut I observed that sometimes when I start the car slowly in reverse and push the brake pedal, it is very hard to push (like pushing on a rock, it doesn't move almost at all, though if I push harder the brake works). It happens only sometimes and only in reverse. Could it be because it didn't prepare that pressure yet at that moment?

The mysteries are being uncovered. I always wondered what the noise was when I opened the door. Now i know its the brake system pressurizing. Thank you!

[@TheCarCareNut]

Hi Toby! Thank you for watching my videos. Regarding the brake fluid I would invest in a brake fluid tested which checks for moisture content. However on average replacement every 3 years is around when the moisture content is high enough to justify replacement.

[@mana9013]

Holy cow i havent change my brake fluid since i bought my highlander....6 yrs

[@TheReubenBonnici]

Great video. Can you someday explain why regen braking disconnects when braking over bumps?

[@journeytowellness7096]

It sounds like you might be experiencing the antilock braking system activating.

[@lsorense]

If one wheel hits a slippery spot the differential causes the other wheel to loose the ability to regen brake. It feels weird.

[@aspecreviews]

If you hit a big enough bump, that causes a power surge, and to protect the hybrid system the regenerative braking disables itself.

[@chamroeunso8772]

Thank you for your showing

[@shanesundet4208]

Interesting system. Couple of questions and a suggestion/request... With little traction on ice and snow,how quickly does the system engage hydraulic front and rear brakes so as to not unweight the back end and keep vehicle stable? 2) it sounds like 90 percent of the braking in these vehicles are done by M2 attached to the front wheels... Does this cause more tire wear on the front and should owners take that I to account when scheduling tire rotations? And a suggestion would be when talking about some parts like the braking cylinder/simulator, could you add in some b roll of the part or a photo? Great content as always ..

[@TheCarCareNut]

Hi Shane! Hope you’re doing well. The hydraulic system kicks in very rapidly on hybrid when needed and bypasses regenerative braking rapidly when needed. It actually has much more control on ABS and traction control due to the accumulator and pump setup. It does cause more braking on the front wheels but that is also true with most front wheel drive cars because of the weight distribution being more towards the front because of the engine and transmission location. That’s why rotating the tires at the set interval which is 5k miles in Toyota’s is important to distribute the wear evenly on all 4 tires and not end up with worn front tires and almost new rear tires. Thank you for the suggestion! I’ll try to include more pictures in my videos.

[@petershen1984]

6:14 a few minutes after parking, the brakes are brought to the "resting" state where only the front wheels could be pumped. Opening the door tells the system to reconfigure the fluid valves for driving. It's very different from the vacuum brake assist!

[@aspecreviews]

The term "skid control ECU" is intentional. Through a system known as vehicle dynamics integrated management, the skid control ECU integrates anti-lock brakes, traction control, and stability control into a single unit via the brake by wire system. The system can help a skid be prevented before it occurs, rather than reacting once it starts.

[@kamk27]

[@kubanskiloewe]

i wonder always when people in Hybrids complain about brake pedal feel. In my old Lexus RX Hybrid i feel exactly the same as in any other car; i can brake very smooth and didnt notice when its going from recup to brake pads. Perhaps thats becasue its so huge and heavy ? Only when coming to a stop the last half meter or so its a bit harsh and stops. What i can feel is sometimes in warm weather or hot brakes when pressing fast, but not hard, on the pedal i can hear the pads (perhaps the rear more) clunking a bit onto the discs; its not a bad sound at all. Thats when the computers decide to do a "real braking" instead of recup becasue the idiot behind the wheel did not held enough distance to the guy in front of him :-) Yeah, Hybrid driving is basicly a very conservative and relaxing drivng...anything other than that increase gas consumption. !

[@Fajoekit]

Hi, thanks for this informative video. I watched this video earlier this week and today I was driving my Lexus GS450h and trying to discern when I was regenerative breaking vs hydraulic breaking whilst pressing my brake pad. I was hoping you could answer my questions about this system. How do I know how far I can press the brake pad before it activates the calipers? How do I know the hydraulic breaking system is engaged, alternatively; how far can I perss the brake pd before it engages the hydraulic system?

[@TheCarCareNut]

Thank you for watching my video. So it’s hard to tell which brakes it’s using. Here’s a few things that might help. When coming to a stop slowly you’ll notice at some point that the brakes get stronger that’s the definite pull of the hydraulic brakes. Then you can drive the car to say 30mph then put the car in neutral and press the brake then put it back in drive and press the brake and see the difference. In neutral the regen braking is 100% off and you are using 100% hydraulic brakes.

[@Fajoekit]

@@TheCarCareNut Thanks for responding! I've actually tried your first suggestion a few times today at around 40kp/h. The Lexus is so silky smooth I barely feel the difference unless I really stomp on it. The switch to neutral is indeed an interesting one. I'll keep it in mind and try it out soon, thanks!

[@TheCarCareNut]

You’re welcome! On Lexus models it could be harder because of how insulated and smooth they are. If you ever get a chance to drive a Prius or corolla hybrid it’s very obvious when the hydraulic brakes engage

Wife's rav4 dying after 15 years she is thinking of getting the new 2021 rav4 hybrid so ran through the whole series, looking out my window at my 70 mach 1, electronics you say hmm LOL

[@TheCarCareNut]

😂 I think the horn on newer cars is more complicated than the 70 Mach 1! Cars have gotten very complicated but Toyota still manages to keep things reliable even with all the complication

[@Atruma]

Never knew my car was so cool! Love watching this series and learning about my beloved prius! Did you work for toyota to become a master tech on their cars? Currently being taught to work on mil vehicles. Sounds like a cool career path idea when I get out!

[@TheCarCareNut]

Thank you for watching my videos! I went to school for Toyota training then worked at the same dealership from entry level to master diagnostic technician! It’s a good career but hard and stressful.

[@coloradoboo1071]

You didn't mention the parking brake but, from what I've seen when underneath my hybrids, they are just the old school parking brake with a cable to the rear wheels which tightens the calipers/pads to the rotor to hold it? (Which is important to use when parking at an incline since we don't want to bend/break the parking gear inside of the E-CVT.) Our Mazda has the electronic parking brake which has a little motor on the rear brakes that engages/disengages...I'm kinda glad Toyota hasn't put these in the Prius, yet!)

[@gunter4822]

I like every video. Great

[@hicububern]

Thank you for your video now I understand why my brake on Prius 2010 is very very hard to press. By the way I bought a new brake actuator , we replace it with new brushless in , but the brake still hard and is not possible to reset it with launch tool. How can we do now ???

[@michaelscottland4239]

Thank you so much for this really cool informative episode on the hybrid break system. I was wondering why I’m still driving my 2018 Camry Hybrid LE with 68k+ miles with my original breaks whereas my friends have to change their break pads twice already with their 2018 Rav4 with 48k+ miles. By the way Mr. AMD, would you mind letting me know when I should be changing my brake fluid? edit: I live in New York City and bought this car around November 2018. Thanks 🙏.

[@allansirju6077]

Great video, keep the knowledge flowing, is the Lexus 2012 CT 200h a better bet over the Prius c .?

[@TheCarCareNut]

Thank you for watching my video. They are two different cars with similar hybrid systems. I wouldn’t say one is better than the other. I would say that the ct is definitely better because it’s slightly bigger and it’s a Lexus but in terms of reliability they are equal

[@jwilczynski]

So if you use hydraulic brakes so rarely in hybrids how do they prevent brake discs from rust? :) By the way - thank you for all of your movies, they’re great! I find a lot of help here :)

[@TheCarCareNut]

Hi Jan! So if you live in an area with salt use I would take them apart and clean things up every couple of years. If not then every few months or when you see rust forming as you drive put the car in neutral briefly and apply the brakes. When in neutral it uses the hydraulic brakes 100%

[@jwilczynski]

@@TheCarCareNut thank you again! :)

[@tommykirouac4649]

Hey!! I can hear my actuator runing about every third time i press the brake for abour 2 second. Is this normal? How often should i hear it. Thank you so much for your videos your are the goat!

[@TheCarCareNut]

Hi! That’s normal.

[@elainehammonds3059]

You mentioned that brake fluid is not on the regular maintenance schedule but you recommend changing it out. How often? Thank you!

[@TheCarCareNut]

Hi! The brake fluid needs to be checked for moisture content but on average every 3 years

[@sedatnet]

Another very informative video, thanks, just wonder there is not any snow mode which disables regenerative breaking for safety on slipper surfaces unlike other EVs. What you recommend for that? Engine breaking B mode? Or any other suggestions?

[@TheCarCareNut]

Hi! The system is very smart and actually it works pretty well in snow as it has complete control over ABS and traction control. Engine B mode is used for mountain driving to slow down the car without using the brakes as much

[@TheReubenBonnici]

@@TheCarCareNut by the way, when going downhill and using B mode depending on the speed the engine makes a lot of noise. I am always afraid of damaging the engine. Does it damage the engine? Can you explain in a video how the engine works in B mode please?

[@TheCarCareNut]

You won’t damage the engine. However excessive use of that mode when not needed is also not good long term.

[@bcosmin2051]

Hello sir . I have a stupid question. Let's say I'm on a mountain road and I have to go down. Let's say that at the beginning the road is quite straight and the car goes in D. After 100 meters the road is no longer straight and starts to descend over a distance of 5 km. I understand that it would be good to put the car in B. But how do I do this? Do I put from D to B while the car is going or do I first have to brake at 0km / h and then put from D to B? I own the Toyota Corolla 1.8 hybrid 2020. Thank you and thank you for the video.

[@TheCarCareNut]

Hi! Thank you for watching my videos. Just switch from D to B without issues. Once the road straightened out go back to D and you should have no issues.

[@MrWawer]

Another great video:-) I was sure that this sounds is the fuel pomp pressurizing the fuel system. New thing learned thank you. BTW in my 2018 PP I have and old-school foot break on the left so I guess it could be use as well in case of failure?

[@TheCarCareNut]

Thank you for watching my video! So the foot brake is the parking brake. That one is mechanical and can be used at any time and that’s connected by cable.

[@smaxwell4062]

@@TheCarCareNut Always good to have a back up system

[@MrD1maS]

Hi, AMD! Correct me if I'm wrong. The fluid is uncompressible, so that accumulator should consist a chamber precharged with nitrogen or similar gas. You can find similar design on the aircraft hydraulic system.

[@TheCarCareNut]

Hi! That is correct and often times when the accumulator fails a hair line crack causes a leak which produces air in the brake system

[@briannickson6631]

Hi, love your videos but you never seem to mention the C-HR. I own one and love it.

[@morninglighttaiji]

Good video 🙂. Was wondering what happens if the batteries are full 🤔

[@make4all2000]

Very interesting video, but I was curious to know how mg2 works when you put the gear shifter in position B.. Thanks!

[@TheCarCareNut]

The video on b mode is coming up tomorrow
